I know most of us troll Hackaday, but just in case you don’t. This guy’s step through making slew bearings in fusion360 is freaking awesome. I might have to print one now…

Did you see his 3d printed brushless motor?

Looks like you might be able to make a pretty sweet scara arm with those bearings. This might open the door to much larger DIY bots.

Yea, his test to fail was pretty cool to watch too!
